Best thing to do is talk with them. Maybe come up with a crisis plan, so you know what steps to take. That's what most of my Ts have done with me. It makes things a lot easier. And also come up with a plan to try to recognize a crisis before it even starts. Sometimes it's too hard because you can go from normal to crisis in a minute. But other times you can learn your signs, and maybe reach out before a crisis. That's what T and L prefer me to do.
